In Wipe Tools, use Partition Wipe, and Disk Wipe

Disk wipe is OK, I select the disk to wipe, then Start (instead of Next...). Drive Wipe should become Partition Wipe, because I can select individual partitions to wipe. It's also confusing, because by checkmarking a partition, the disk will also be checkmarked. If I don't want to wipe the MBR, only all partitions, the disk should not be selected, or should be selected in gray.
